Agile Architecture
1 like797 views
The document discusses what software architecture is and when it occurs in agile development processes. It defines architecture as the significant design decisions that are hard to change and influence the overall system structure. These decisions include high-level software structures and flows, as well as the desired user experience. The document notes that while some decisions can be determined up front, architecture truly emerges and evolves throughout development as guided by user stories and refactoring.

- 4. “It’s a set of training wheels for developers who don’t know how to apply the SOLID principles in practice.”
- 5. “It’s how vendors make money.”
- 6. “BDUF.”
- 7. “UML.”
- 8. “Spring?”
